What is a common function of hydrators in skin care products?

Hydrators are key ingredients in skin care products designed to maintain or restore moisture levels in the skin. Their primary function is to retain moisture, which is essential for keeping the skin plump, elastic, and healthy. When hydrators are applied, they work by attracting and binding water to the skin, which helps to prevent dryness and improves overall skin texture.

Maintaining adequate hydration is crucial as it supports the skin's natural barrier function and can enhance the effectiveness of other skincare ingredients. This is particularly important in esthetics, where healthy and well-hydrated skin often reflects better results from treatments and procedures.

While some ingredients in skincare may provide color, exfoliate, or serve as preservatives, those roles are distinct from the primary function of hydrators. Their efficacy in moisture retention is what makes them a staple in most moisturizing skincare formulations.
